Am i Pregnant or Not. Please help

Patient: I would like to know if i am pregnant. 7 postivie tests 6 were clearblue and 1 was first response but 1 negative when i went to the doctors. missed my period on the 27th feb then had a little bleeding on the 9th of march. it started off as brown and light then next day went light pink and a little heavy then back to brown and light as lasted 4 days. they reckon i would be around 7 weeks along but im just really confused. the last test was taken on the second day of the bleeding and was first response. please help.
